An error was encountered when attempting to define a file that contains both a class and an interface with an expected sem

Seeking guidance on creating a Typescript file with a class and interface:

export class Merchant {
  constructor(
    public id: string,
    public name: string,
    public state_raw: string,
    public users: string,
  ) {}
};

export interface MerchantList {
  constructor(
    public id: string,
    public name: string,
    public state_raw: string,
    public users: string,
  ) {}
};

Encountering an error that says '; expected.' at this line ) {}. Any suggestions on how to resolve this issue?

Answer №1

Interfaces in programming serve as blueprints for properties and methods that can be implemented by various types. Because of this, interfaces do not have constructors. Perhaps what you were looking to define is:

export interface MerchantList {
  id: string;
  name: string;
  state_raw: string;
  users: string;
};
